Application filed June 11, 1920.- Serial No. 388,371

To all whom it may concern:

Be it known that I, Tniio'conn J. hfTI-GCHEL- .nnirrn, a citizen of theUnited States residing at Cleveland, in the county of (luyahoga andState of Ohio, have invented a certain new and useful lmprovcn'ientin.1,;l3urner Constructions, of which the following isa full, clear, andexact description.

This invention relates to a burner construction which is so constructedthat the application of heat incident to burning a fluid fuel, beneath areceptacle being heated, is made directly to the receptacle and notthrough any considerable air space between the burner and receptacle, asis the case with usual types of burners.

The invention further contemplates a construction which can be employedwith combination coal and gas ranges ot'a type wherein the anchor plateof the range serves as a common top plate whether gas or coal be used asa source of heat, the burners being a permanent structure in the range.I

Reference should be had to the accompanying drawings forming a part ofthis specification in which Fig. 1 is;a front elevation of a portion insection of the range embodying the present invention: Fig. 2 is in parta top plan and sectional view showing a portion of the range; Fig.8 is atop plan view of a burner; i l. is a sectional elevation showing aburner and cooperating plate.

Referring to the drawing, 1 indicates a suitable standard having legsupon which the body of the range proper is supported. At 2 there is.indicated an elevated or upright portion provided with doors 3 and 4behind which are located respectively an oven and a broiler compartment.

Located centrally of the range or otherwise positioned, and dependedwardly, is a fire box construction 5 which is provided with a usuallining 6. grate bars indicated in dotted lines at 7 and adoor 8, all ofwhich are of usual construction. i

The top plate of the range is indicated at 9 and beneath the top platethere is a lower plate such as indicated at 10 and the space between thetop plate 9 and 10 is closed in so as to provide a chamber which is inopen communication with the fire box.

down- The rear wall of the chamber 11 is provided with openings such asindicatedat 12, whichopeningscommunicate with afliie passageway within ahousing member 13.

no or more of these openings may be con+ trolled by a damper. l

The anchor plate 9 is provided with two openings, which openings areoccupied by the removable plates 1 1 and 15. Each of the removableplates is-provided, with oneor more openings such as indicated at 16 inFigs. 1 and 4. I ithin the chamber 11 and b611821t11 -tl18 removableplate is located .a burner istruc ture which is generally indicated at17. This burner structure as shown in Fig. comprises an endless hollowtube 18 which is connected with a supply pipe at 19. In the presentinstance the burner is annular in form corresponding with the opening 16in the plate 14.

The burner structure with lugs such as 20 which the burner is directlyattached to the removable plate such as the plate 14. p

The burner is located so as to lie just beneath the plate 14: and.extending around the edge of the opening in the plate. The tubular bodyof the burner is drilled with a plurality of holes as indicated at 21each of the holes being located adjacent one side of the top of theburner anjd'the angleof the holes is such that the flame incident tomaybe provided burning gaseous fuel is directed toward the center ot theopeningl6inqtheplate 14:.

It will be noted that the flame from the burner is practicallylocateddirectly be-- neath the plate 14 and the flame directly contacts withthe receptacle which may be placed over the opening 16. The distancebetween thetop of the plate 14 and. the holes 21in the burner is butarveryshort distance so that the flame and the hot gasesof combustionpass through a very limited air space in the application of heat. Thisresults in a more direct application of heat and less wastage thanis thecase where in the usual type of gas range the burner is located 2 or 3inches below the top surface of the top plate of the stove and becauseof this distance a considerable amount of heat is'lost Due to the factthat in the present burner the holes are directed inwardly the flameshoots toward the center of the opening in the plate 14: and hence willsubstantially with the gas header 22.

said opening, means for supporting The burners being located directly beneath the top plate of the range may remain in the chamber 11 eventhough the burners are not in use but the heat supplied by the burningof fuel in the fire box 5.

lVhen solid fuel is used, the openings in the top of the plates let and15 are closed by means of a cover member indicated at 23, which fits ineach of the openings 16. Each cover is provided with a depending flange24 which extends inside of the burner structure and so protects theholes in the burner from becoming filled or clogged with coal dust orash dust when a solid fuel fire is used.

As will be understood, the pipes which connect the various burners withthe gas header 22 are provided with the usual valve and air mixerconstruction such. as indicated at se Having described my invention, Iclaim 1. The combination with a top plate of a range, which top platehas an opening therein, of a burner comprising an endless tubular bodycorresponding in form with the said opening, means for supporting saidburner directly beneath said plate and close thereto, said burner bodyhaving holes thercin which are positioned to direct a flame toward thecenter of the opening in the said plate.

2. The combination with a top plate ofa range, which top plate has anopening therein, of a burner comprising an endless tubu lar bodycorresponding in form with the said burner directly beneath said plateand close thereto, said body having holes therein, which holes areadjacent the edge of the opening in the plate and positioned to direct aflame toward the center of the flame in the plate. 1

3. The combination with the top plate of a range, which top plate has anopening therein, a removable plate" in said opening, said plate havingan opening therein, a burner comprising an endless tubular bodycorresponding in form with the said opening, means for supporting thesaid burner from the removable plate directly beneath said plate andclose thereto, said body having holes therein, which holes are adjacentthe edge of the opening in the removable plate and positioned to directa flame toward the center of the said opening.

4. The combination with the top plate of a range which top plate hasan'opening therein, of a burner comprising an endless tubular bodycorresponding in form with the said opening, means for supporting thesaid burner directly beneath said plate and close thereto, said bodyhaving holes therein which are positioned to direct a flame toward thecenter of said opening and a cover adapted to .fit in the opening of theplate, said cover having a depending flange which extends inside of theburner body.

5. A range comprising atop plate, saidtop plate having an openingtherein, means enclosing a chamber beneath said plate, a tire box whichis in open communication with said chamber, a burner comprising anendless tubular body, means for permanently supporting the burner withinthe said chamber beneath the edge of the opening in said plate and closeto the plate.

6. A range comprising a top plate, said top plate having an openingtherein, means enclosing a chamber beneath said plate, a fire box whichis in open communication with said chamber, a burner comprising anendless tubular body, means for permanently supporting the burner withinthe said chant ber beneath the edge of the opening in said plate andclose to the plate, a cover adapted to close the opening in the said topplate, said cover being provided with a depending flange which extendswithin the body of the burner.

In testimony whereof I hereunto aflix my signature.
